In typical color Doppler displays, which color corresponds to positive Doppler shifts?

Explanation:
Positive Doppler shifts come from motion toward the transducer. To convey direction quickly, the standard color map in color Doppler uses red for flow toward the transducer and blue for flow away. So red is the color that represents positive Doppler shifts. (Some machines offer alternative palettes or use green/yellow for other display features, but the sign of the Doppler shift is conventionally shown as red toward and blue away.)
